DESCRIPTION
The MTR105 is a dedicated Static Motor Tester with Megger’s tried
and trusted suite of insulation resistance tests (IR), plus all the great
traditional features and reliability of Megger’s testers.
The MTR105 takes the test abilities of Megger’s proven IR test
instruments adding DLRO four wire Kelvin low resistance test,
inductance and capacitance tests to provide a versatile motor tester,
all packaged in a robust hand held instrument, which up to now has
simply not been available.
Additionally the MTR105 incorporates temperature measurement
and compensation (for IR tests), motor direction of rotation plus
supply phase rotation tests.
These new test abilities make the MTR105 a real world, versatile,
hand held motor test instrument.
The MTR105 comes in an over-moulded case, providing increased
protection and robustness, achieving an IP54 weatherproof rating.
FEATURES
n Guard terminal, to eliminate any surface leakage current.
n Detachable test leads with interchangeable clips and probes
for different applications.
n Stores test results for up to 256 motors, which can be
downloaded to a USB mass storage device.
n Rotary dial control, full graphic display, simple and easy to
use.
n Environmental protection to IP54, providing protection
against moisture and dust ingress, including the battery and
fuse compartment.
n Tough housing: A ‘rubber over moulding’ combines a tough
shock absorbing outer protection with excellent grip, on a
strong modified ABS housing, providing a robust case.
n Rechargeable batteries with mains charger kit option.
APPLICATIONS
n Production tests for new manufactured motors and
generators.
n Test repaired and refurbished motors and generators.
n Monitoring and maintenance of in service motors (off line)
in the field.
TYPICAL INDUSTRIES INCLUDE
n Utilities: Electrical power generation, water, oil / gas.
n Industrial: Production line / factory maintenance teams,
HVAC field engineers.
n OEM: Motors / generators.
n Service: Motor repair workshops.
n Transport: Rail, electric vehicles, marine, etc.
SAFETY
The MTR105 is designed to be exceptionally safe to use. The fast
detecting circuitry reduces the likelihood of damage to the instrument
if accidentally connected to live circuits or across phases.
n Meets the international requirements of IEC61010 and
IEC61557.
n Live circuit detection and test inhibit on all measurements
with user notification (except for direction of rotation
measurements).
n User selectable insulation test terminal lockout voltage
25 V, 30 V, 50 V, 75 V (default is 50 V).
n Detection and inhibit functions when the protection fuse
has failed.
n Suitable for use on CAT III applications and supply voltages
to 600 V.
